DNA sexing

Do you have a question about anatomy, life cycle, taxonomy, or anything else that isn't covered by the other frogs.org.au projects? Ask them here (or provide an answer to other people's questions).

DNA sexing

Postby toadie » Fri Apr 26, 2013 12:55 pm

I've kept birds for a few years now and I know its possible to get species that are sexually monomorphic dna sexed. Is it possible to do the same with frogs.

As chance would have it, an article was recently published in the Journal of Herpetology looking at sex identification in Geocrinia: http://www.bioone.org/doi/abs/10.1670/11-290

The short answer is yes - though rather than DNA, Hogan et al. looked at the ratio of hormone metabolites in the frogs' poop.

I'm sure DNA sexing would be possible from toe or web clipping as well, although not likely to be cheap/widely available, perhaps apart from use in conservation programs. The sex of many adult frogs can also often be determined by call, the presence or absence of nuptial pads during breeding and throat colour.

Cheers,
David.
